$20-25 is the going rate in my neck of the woods. AS New ones always seem to SIT on the dealers tables for $30-40. For other than Colt brands, $18-25 depending on condition.
The shops here in town are a different story. One fella wants $35 for worn Colts. Another wants $50 a piece. Then there is another guy that really thinks he has the market cornered...He wants $55 for a couple with 20% finish, $300 for 4 Colt 20's NIW (4-pak that I traded to him a couple years ago now) and $450 for 7 Adventureline 20s NIB (Box of 7) Needless to say, these guys don't sell many mags. [rolleyes]
The best I did was a going on a couple years ago now at a fun show...Bought 22 Colt 20s for $220...$10 EACH! [jump] They're early contract with the allow follower in as new condition. Aside from some handling marks from being thrown in a rubbermaid tub together they had never been inside a receiver. (Been looking for that kind of deal again ever since)[peep]
Due to the sunset coming up in less than year, buyers are skeptical. But if I needed some mags, I would pay up to $30 for a new Colt 20. ($25 for AdventureLine, etc) I figure since LE are paying $17 for Colt 20s (Less for other brands in quantity) I ain't worried about paying an extra $10-15 for the mags I NEED NOW.
As far as I know, and I may be incorrect, the military will not be releasing mags to the civilian world after the sunset. I believe Billy Clitton put the axe to that idea above the AWB...[pissed]
